COOKING-STOVE The Schedule referred to in these Letters Patent and making part of the same.

I, MARTIN J. Mosman, of the city of Troy, in the county ot' Rensselaer, and State of New York, have invented certain Improvements in Hot-Blast or Hot- Air Draught for Cooking-Stoves. of which the following is a specification My invention consists in the arrangement and construction df ues or chambers, situated back ot the tire-pot ofa cooking-stove, between it and the oven of the stove, the said chambers or fines being arranged one above the other, and divided from each other by a horizontal flue-strip; and also the said ues orchambers provided with apertures for the admittance of air thereto, .and for its passage therefrom.

4It also consists of the arrangement and construc- -tion ot' three flues or chambers, situated between the front plate of the stove and the front plate oi' the irepot,'said chambers divided from each other by vertical due-strips, and also provided with apertures for the admittance of air thereto,`and its passage therefrom.

' Italso consists in providing a means of communication between the chambers or tlues front of the tirepot, and those tlues back of the fire-pot, so that currents of air may enter the flues between the {ire-pot and the oven, pass from the same across the ends of the fire-pot, between the end-plates thereof` and the jambs of the stove, and from thence, through apertures, pass'to the il ues front of the tire-pot.

It also consists in the construction and employment of peculiar-shaped vertical tine-strips, which divide the front fines, shaped so that a triangular aperture is formed, having its widest part at the top, for the purpose of causing the air to rise, in its passage from the two corner tlues or chambers, to the middle ue or chamber. v

It also Aconsists in an arrangement and construction of dampered apertures, `for passage of air from the said middle chamber or flue, one situated at the upper part, and one at the lower part of said tine, so that ir may 'be admitted above the tire, or beneath the tire, or both at once, as most desirable.

-The Vobject of my arrangement of'tlues or chambers, and the construction thereof, is to furnish the burning fuel with hot or highly-heated air for draught, or to assist in the decomposition of gases, all of which it does most eectually.

General Description.

On the drawings, like letters refer to like or corresponding parts.

Arrows show the directions of the air-currents.

a represents the aperture for the admittance of air,

from outside the stove, to the upper flue or chamber, back of the fire-pot. Y b represents the upper flue or chamber, covered by the plate b1, and divided from the lower iue or chamber by the plate bi, and divided from theA firepot by the plate b3,- and from the oven of the stove by the plate bi.

At c is the aperture for the passage of air from the flue b to the chamber or tine-space d, which is formed by the plate lll, which divides it from the tire, andthe jambbf the stove d2, which divides it from the outer air.

At e is the aperture through which the air passes to the corner chamber or flue, in front of the fire-pot.

The chambers or tlues in front of the tire-pot are formed between the i'ont wall of the fire-pot r1 and the front ofthe stove fzthe jambs of the stove forming the outside ends.

The space thus formed is divided into `three fines or chambers, by the division-plates q, and covered by the top plate of the stove, q1, and closed, at the bottom, by the plate q2.

l The two corner fines or chambers are marked, rei fire-pot, situated on the opposite side of the stove from the one before mentioned, and marked (I, and is constructed in a similar manner. This llue-space or chamber is marked 74.

At L is the aperture for the passage of air therefrom to the corner flue or chamber, marked f1.

The air, having arrived in the two corner chambers or fines f and f1, is then admitted into the middle fine or chamber l, through apertures formed in the plates q, and marked p. l

At lig. 9, one of these plates is shown separately. The dtted line shows the line of the plate r1, which divides the fines from the nre-pot.

The air rises and passes, through the apertures p, into the middle Hue or chamber' Z, and from thence is admitted to the tire, through the dampered apertures at m, in the bottom of said chamber, or through the dampered apertures at the top, .at n.

lr represents the fire-pot, having its grate shown at s, and is constructed between the plate r1, which forms the front thereof, and the plate b3, which forms its back, and the plates l1 d", which form its ends,

The remainder of the stove is constructed as usual.

The operation of the arrangement ar d construction described above is as follows:

Air is admitted on the one side, through the aperture a, to the flue-space or chamber b thence, through the aperture c, tothe space d; thence, through the aperture c, to thefront corner space or flue f,- i'rom thence,

through vthe aperture p, to the chamber l; and from thence, through the dampered apertures on n, either above the lire or below the fire, as desirable, or through both at once.

On the other side, airis admitted, through the aperture g, to the ue or chamber 71,; through the same to the aperture t' thence, through the flue or chamber j, to the aperture 7.1,- through the corner flue or chamber f1, over and through the aperture l), to the middle flue or space l; and from thence is admitted to the fire, througli the dampered apertures m and n..

By shutting the lower damper and opening the upper, the lire is checked, this Vdamper acting as a check-draught damper; and when the lower damper is opened, by opening-the upper one partially, air may be admitted at the top iu suitable quantities, to assist in the destruction of gases, while the main body of the air is carried around under, for draught, and in this way the burning fuel is supplied bya never-failing current of `very highly-heated air.

In rig. 1l is' shown another form, which maybe used for flue-strips, dividing the front chambers. In this case the air passes over the-top, at u, into the middle chamber l.

A supply of fresh air may be admitted to the chambers or ues (b and 11.) from beneath the stove, as shown by dotted lines on 3, if thought best.

Claims.

I claim, as my inventionil. The two horizontal tlues or chambers b and h, divided by the horizontal Hue -strip b2, and iu combination therewith, and having apertures for ingress and egress of air, substantially as and for the purpose described and set forth.

2. The three dues or chambers f, f1, and Z, situated, constructed and, used for the purpose as described and set forth.

3. lhe two dues or chambers j and (l, in combination with the chambers or ues l) and h, and the chambers or lines f andf, as and for the purpose described and set forth.

4. The horizontal flue-strip b2, substantially as de scribed and set forth.

5. The flue-strips q, constructed. situated, and used substantially as described and set forth (i.vl The dampered apertures m and n, situated, constructed, and used, substantially as described and set forth.
